Application filed June 20, 1927, Serial No 200,156, a'ndiin Canada March 1, 1927.

This invention relates to a cable'conveyer sprocket as described in the present specification and illustrated in the accompany ng plate being formed with-the projecting'lug drawings which form part of the. same.

The invention consists essentially of the novel features pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to provide a cable, conveyer sprocket so built that it will retain the conveyer cable thereupon in case the usual cable button engaging the usual gap slipsover the cable; to provide wearing parts which are easily assembled upon and removed from the sprocket; and generally, to manufacture an eflicient and improved gap wheel capable of accomplish ing the aforesaid purposes.

In the drawings, Figure mentary side elevation view of the parts being shown in section;

Figure 2 is a section taken on line 2-2 inFigure 1;

Figure 3 is a cross section of the wheel rim;

Figure is a front elevation view of the T-bolt fastening the renewable groove seg ments to the wheel body;

Figure 5 is a side view of Figure 4;

Figure 6 is a fragmentary bottom plan view of the rim showing the bolt slots;

Figure 7 is a fragmentary side sectional view of the removable segments showing Figure 8 is a are 7.

Like numerals of reference indicate corresponding parts in thevarious figures.

Referring to the drawings, 10 is v the sprocket, having the rim 11, the hub 12, and the usual spokes 13, the hub and spokes forming the web section of the sprocket.

The rim is formed with the desired number of gaps 14 sized to receive and enclose the spaced buttons 15 of a conveyer cable 16, the cable engaging 'the detachable grooved segments 17. The rim, where out off to provide each of the gaps 14, is formed with the horizontally-arranged bottom flange 18 and wheel.

bottom plan view of Fig-- or portion 21 engaging a suitably+sized groove depressed into said flange 19; the

wearing plates are fastened in their operas tive positionby means Of suitable bolts 23,

the plate being counter-sunk to receive the head of each of said bolts, as best shown in Figure 1.

The rim extends out on each side to form flared out flanges 25 and a relatively wide substantially semicircular groove 26 sized to receive and hold the button there within should it slipover the cable. The

buttons are spaced along the cable to engage 26 and thecable would not be thrown off the The detachable segments 17 are formed with the substantially semi-circular recess 27 sized to receive or be engaged by the cable, the segments extending between the gaps. v l I 7 he segments are secured tothe rim-by means of the T-headed bolts 27 to allow clearance for the introduction therethrough of the T-bolts; the detachable segments have rectangular slots 29 terminating in a rectangular cross hole 30 having the recess 31 sized'to receive the head of one v The rim I has the rectangular holes or slots 28 sized ofthe T-bolts; ,The recess 31 forms means of locking each boltiagainst. rotation while its nut is tightened against the under side of the rim.

The segments, which extend between the gaps, are'made approximately. as long as the clear distance between any two gaps and.

the wearing plates- 20, once secured in posi-' tion, form means of preventing any'longitudinal'movement of the segments relative tions spaced to provide gaps: therebetween. adapted to receive the cable buttons, said tions spaced to form gaps therebetween adapted to receive the conveyer cable lout-v tons, Wearing plates secured in said gaps, and detachable grooved cable segments sccured upon sald rim sections and substantially engaging at the ends thereof two of said Wearing plates. 7 i 6 v Signed at the city of Toronto, May, 1927. i RICHARD LYDSTONE SMALLWOOD.
